AIRCRAFT RESCUE AND FIREFIGHTING VEHICLE CLEANING FOR AFFF REMOVAL
Lang, J. and D. Kay. SERDP & ESTCP Webinar Series, February 2026
Filed Under: General News
Filed Under: General News
This SERDP and ESTCP webinar features innovative approaches and technologies for PFAS removal and/or destruction from fire suppression systems impacted by residual PFAS due to the use of AFFF. The Department of War (DoW) has many fire suppression systems impacted by residual PFAS due to the use of AFFF. At elevated concentrations, PFAS self-assemble and coat surfaces at liquid/solid interfaces, forming waterproof coatings. Recent work demonstrated that water-only rinses may not adequately clean some system components. However, the cost of replacing all existing PFAS-impacted AFFF delivery infrastructure across DoW installations would be expensive and result in equipment downtime. The first presentation showcases insights from disassembling and analyzing PFAS residual content on foam system components from the Oshkosh T-1500 Aircraft Rescue and Firefighting vehicle. Results provide critical information on mission-relevant considerations for fully remediating equipment after baseline treatment, including costs for replacement of the on-board foam system, out-of-service time required for cleaning, and the extent of replacement required to successfully achieve PFAS removal from an on-board foam system. The second presentation features the PFASigator, a treatment unit that provides a practical, effective, and scalable solution for successfully remediating firefighting systems historically exposed to AFFF. Through employing a micelle‑enabled photoactivated reductive defluorination reaction, the solution provides simultaneous PFAS desorption and destruction. The presentation shares results from a field demonstration performed at Tyndall Air Force Base, where PFASigator was connected to a decommissioned firetruck's AFFF tank and associated piping to form a closed recirculation loop. The integrated process of PFAS desorption and destruction removed and mineralized 16.8 grams of PFAS within 48 hours. https://serdp-estcp.mil/events/details/9efc643a-c67f-4035-872a-ae46cb7d0976/aircraft-rescue-and-firefighting-vehicle-cleaning-for-afff-removal
